find can traverse and search through different file systems of partitions belonging to one or more storage devices mounted under the starting directory. [ 1 ] The possible search criteria include a pattern to match against the filename or a time range to match against the modification time or access time of the file.
pax is an archiving utility available for various operating systems and defined since 1995. [1] Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility pax that could support various archive formats with useful options from both archivers.
A screenshot of the original 1971 Unix reference page for glob – the owner is dmr, short for Dennis Ritchie.. glob() (/ ɡ l ɒ b /) is a libc function for globbing, which is the archetypal use of pattern matching against the names in a filesystem directory such that a name pattern is expanded into a list of names matching that pattern.
The Slurm Workload Manager, formerly known as Simple Linux Utility for Resource Management (SLURM), or simply Slurm, is a free and open-source job scheduler for Linux and Unix-like kernels, used by many of the world's supercomputers and computer clusters. It provides three key functions:
The rdiff-backup script maintains a backup mirror of a file or directory either locally or remotely over the network on another server. rdiff-backup stores incremental rdiff deltas with the backup, with which it is possible to recreate any backup point. [33] The librsync library used by rdiff is an independent implementation of the rsync algorithm.
{tagfile} – The name of the file where {tagname} is defined, relative to the current directory {tagaddress } – An ex mode command that will take the editor to the location of the tag. For POSIX implementations of vi this may only be a search or a line number, providing added security against arbitrary command execution.
The setuid and setgid flags have different effects, depending on whether they are applied to a file, to a directory or binary executable or non-binary executable file. The setuid and setgid flags have an effect only on binary executable files and not on scripts (e.g., Bash, Perl, Python). [3]
